Just Erase some parts of the black layer, following horizontal lines to simulate how an old glass looks.īack in Maya, click on the Texture button next to the Reflectivity option. You can use several different Brush Presets. It has to be a black texture with alpha zones where you would like the glass to become less transparent. We'll also need to create a texture, I'll show how I created the texture using Photoshop. The settings will automatically change, but we still need to make some adjustments to the shader. Click on the Presets button and choose GlassSolid > Replace. Mental ray already has a great preset we can use. Open its Attribute Editor and rename the material to something meaningful and related to the glass. You'll see the shader created in the Work Area. Under the Mental Ray materials, search for mia_material_x and click on it to create a new material. Now we'll start creating the shaders, go to Window > Rendering Editors > Hypershade. The Plug-in Manager window will open, look for the Mayatomr.mll plug-in and make sure to activate it.

Go to Window > Settings/Preferences > Plug-in Manager. To start, we need to activate Mental Ray. In this two-part tutorial, you learn how to build and render a realistic glass of water, complete with accurate caustics in Maya.

Achieving a realistic render can be a challenging task, especially when re-creating a real-world object or scene.
